Ideal camera settings to approximate human eye?
The default in Blender assumes 1 Blender unit = 1 meter, so you're actually on the right track there.

As for the question regarding a match on the human eye, that's a tough one. Not just because of the monocular/binocular thing, but also because your retina is curved and most cameras and digital approximations assume a flat sensor. 

That said, I've done a bit of my own research on this (reading advice from photographers is interesting... not always accurate, but interesting :) recently and landed on the following settings that seem to work reasonably well:


Camera Sensor - 35mm
Camera Focal Length - 45mm


Clipping distances, you'll need to adjust to taste.
